Abstract
A flaw detection car in the body of a high-speed rail bridge relates to a flaw detection device for a bridge body. A plurality of fixing frames (6) are arranged on the wall of a bridge hole (5) from the starting part of the bridge body (1) to a station yard or an ending part, and a slide bar (2) forms a slide rail for the flaw detection car; and the flaw detection car comprises a pulley (3), a connecting rod (12), a belt (11), a casing (4), a motor (15), a wireless signal emitter (14), a supersonic detector (20), a wide-angle probe (17), a storage battery (18), and a control button (19). In the invention, since the arrangement of the slide rail formed by the slide bar and the fixing frames on the wall of the bridge hole inside the body of the high-speed rail bridge, the flaw detection car is enabled to run and detect flaws in the bridge hole conveniently, and the disadvantage that observation can not be performed in many places by using a man and telescope flaw detection way in the prior art, can be effectively overcome. The wireless signal emitter arranged in the flaw detection car disclosed by the invention can achieve accurate positioning to the flaw detection car.
Description
[technical field]
The present invention relates to a kind of bridge beam body failure detector, especially relate to a kind of interior flaw detection trolley of beam body of high-speed rail bridge.
[background technology]
High-speed rail bridge is an indivisible integral body in the high ferro operational system, and the quality of high-speed rail bridge quality often affects operation security and the quality of whole piece high ferro circuit, so the work of high-speed rail bridge maintenance management is an extremely important job.At present, to the maintenance management of high-speed rail bridge, be mainly to repair the hole groove; And to the high-speed rail bridge inspection, be mainly by the artificial visually examine check, hand-kept marking, judge the high-speed rail bridge constructional aspect.If will more accurately judge the bridge practical working situation, for high-speed rail bridge is reinforced or overhaul provides foundation, on the basis checked in high-speed rail bridge outward appearance disease, be necessary to carry out detection and the loading test of the high-speed rail bridge structural meterials of a dark step.So the scientific management of high-speed rail bridge is very important, once the high-speed rail bridge accident occurs, not single economic loss is very big, the political fallout meeting is larger, therefore for improving the detection management level of high-speed rail bridge, the high-speed rail bridge that must pay attention to high ferro detects, and understands working programme, test item and detection method that high-speed rail bridge detects, grasps experimental data processing and analytical method.The high-speed rail bridge test detects as maintenance management provides direct data and foundation, and its work involves a wide range of knowledge, technical sophistication, and difficulty is higher, if adopt advanced checkout equipment can greatly improve precision and the operating efficiency of detection.The difference of the degree of depth in examination scope, mode and inspection purpose wherein, the high-speed rail bridge inspection mainly is divided into high-speed rail bridge running check and the large class of high-speed rail bridge structure detection two; Described high-speed rail bridge structure is undertaken by the manual inspection mode at present, is difficult to enter high-speed rail bridge beam body and is detected, and especially, on river, after storm and flood, to high-speed rail bridge, will add the thorough examination frequency.Common high-speed rail bridge is made regular check on, the cycle be approximately every 3～5 years once.Its objective is the dynamic data of regular collection high-speed rail bridge structure technology state, list the high-speed rail bridge maintenance management system in, for the evaluation high-speed rail bridge is used function, formulates concrete high-speed rail bridge maintenance project master data is provided.Make regular check on usually by there is certain inspection experience and be subject to special high-speed rail bridge inspection training, the maintenance engineer that is familiar with the aspect knowledge such as high-speed rail bridge design, construction is responsible for organizing and implementing.Although bridge running check also part is used simple tool or instrument to be detected, but be mainly the inspection of estimating the bridge outward appearance be main, the evaluation of check result also is based on superficial phenomenon and experience mostly, and real inherent danger is difficult to find, without damaged detection means, bridge is carried out to complete detection so, survey strong and flaw detection, thereby find out the reason of damage, degree and scope, the danger that the consequence that the analysis damage causes and latent defect may be brought to bridge construction, durability and supporting capacity for the evaluation bridge, the embodiment of determining maintenance works provides the principal security of foundation, wherein mainly comprise the damaged inspection of bridge outward appearance, bridge construction and material tests and Test on Bridge Loading three parts.
